Detailed explanation-1: -As polyols with carbonyls, monosaccharides can undergo a series of oxidation and reduction reactions. Reduction of a monosaccharides produces polyols known as alditols or sugar alcohols.

Detailed explanation-2: -Treating an aldose or ketose with sodium borohydride reduces it to a polyalcohol called an alditol. The alditol derived from d-glucose is called d-glucitol. d-Glucitol occurs in some fruits and berries. It is produced and sold commercially as the sugar substitute called sorbitol.

Detailed explanation-3: -For example, the alditol obtained by reducing d-glucose-1-C14 may be named either d-glucitol-1-C14 or l-gulitol-6-C14. An unlabeled alditol that has a plane of symmetry is a meso compound derivable from either the d or the l form of an unlabeled aldose.

Detailed explanation-4: -Alditols, also known as sugar alcohols, are obtained from the reduction of an aldose and are one type of commonly used sugar substitutes.

Detailed explanation-5: -Monosaccharides are easily reduced to alditols (known also as ‘polyols’) by sodium borohydride (NaBH4) in weak alkaline solution. Large-scale reduction is carried out by catalytic hydrogenation. Alditols are linear molecules, do not form rings, and do not exist as anomeric forms.
